The Audit Committee (the “Committee”) of AGL Resources Inc., a Georgia corporation (the “Company”), is a committee of the Board of Directors of the Company. Its primary function is to assist the Board in fulfilling its oversight responsibilities with respect to (a) integrity of the Company’s financial statements and periodic financial reports, and (b) compliance with legal and regulatory requirements. The Committee shall also (a) have direct responsibility for the engagement of the independent registered public accounting firm based on an assessment of its qualifications and independence, and (b) evaluate the performance of the independent registered public accounting firm and internal audit function, and (c) prepare the Audit Committee Report required by SEC rules to be included in the Company’s proxy statement. In discharging its oversight and other responsibilities, the Committee is empowered to investigate any matter brought to its attention with full access to all books, records, facilities and personnel of the Company and has the authority to retain outside legal, accounting or other advisors, at the expense of the Company, to advise the Committee. The Committee shall produce an annual report for inclusion in the Company’s proxy statement for the annual meeting of shareholders, in accordance with applicable rules and regulations. The composition and responsibilities of the Committee are described in this Audit Committee Charter (the “Charter”).

While the Committee has oversight responsibilities and powers as set forth in this Charter, it is not the responsibility of the Committee to prepare the Company’s financial statements or to plan or conduct audits to determine if such statements are complete, accurate and in accordance with Generally Accepted Accounting Principles (GAAP). These are the responsibilities of management and the independent registered public accounting firm, respectively. Management also is responsible for compliance with applicable laws, regulations, internal controls and procedures, and with the Company’s disclosure controls and procedures, internal operating and compliance policies, and codes of conduct and ethics.

I. Composition

In accordance with Article III of the Bylaws of the Company, the Board of Directors, by resolution adopted by a majority of the whole Board of Directors, may designate an Audit Committee. The Committee shall consist of four (4) or more Directors. The Committee shall be composed entirely of independent, non-employee Directors of the Company, in accordance with applicable rules and regulations. Each member of the Committee shall be financially literate, as defined by applicable rule or regulation and by the Board of Directors, or must become financially literate within a reasonable period of time after his or her appointment to the Committee. Additionally, the Board will ensure that at least one member of the Committee will have accounting or related financial management expertise and will qualify as a financial expert as defined by the Securities and Exchange Commission.

If a Committee member simultaneously serves on the audit committees of more than three companies subject to the periodic reporting requirements of the Securities Exchange Act of 1934, then the Board must make a determination that such simultaneous service would not impair the ability of such member to effectively serve on the Committee and disclose such determination in the Company’s annual proxy statement.

The members of the Committee shall serve at the pleasure of the Board of Directors or until their successors shall be duly designated. Vacancies in the Committee shall be filled by the Board of Directors.

The Audit Committee, subject to approval by the entire Board of Directors, where appropriate, shall:

1. Provide an open avenue of communication among the Board of Directors, the internal auditors, and the independent registered public accounting firm for the Company.

2. Review with the Chief Audit Executive of the Internal Audit department (“Chief Audit Executive”) and the independent registered public accounting firm the coordination of the internal and independent audit efforts.

3. Review with management, the independent registered public accounting firm and the internal auditors, as appropriate, audit policies and procedures and the scope and extent of audits. In consultation with management, the independent registered public accounting firm, and the internal auditors, consider the integrity of the Company’s financial reporting processes and controls.

4. Retain and terminate the Company’s independent registered public accounting firm, with sole authority to pre-approve, to the extent required by applicable law, all audit engagement fees and terms, as well as all non-audit engagements with the independent registered public accounting firm. In accordance with applicable law, the Committee may delegate this authority to one or more designated members of the Committee; provided that any such decision made pursuant to the foregoing delegation of authority shall be presented to the Committee at its next regularly scheduled meeting. In connection with its consideration of the retention and termination of the Company’s independent registered public accounting firm, the Audit Committee acknowledges the potential benefits to be obtained from a change in the Company’s independent registered public accounting firm from time to time and will consider such a change periodically as dictated by circumstances, and in any event not less than every three years. Each year, the Audit Committee shall also recommend that the Board of Directors submit for shareholder ratification the retention of the independent registered public accounting firm.
